Spreads on the inner surface 5 of the cylindrical aluminum drum 1. On the other hand, the laser is irradiated before the adhesive is discharged by the reflected light detector 3 whose irradiation light is adjusted to this position. Before ejection, a certain amount of laser light from a laser irradiator (not shown) of the reflected light detector 3 is substantially coaxial as shown by a without being regularly reflected by b due to the unevenness of the inner surface 5 of the cylindrical aluminum drum 1 as shown by b. Light reflects. The amount of light is detected by a light detecting unit (not shown) of the reflected light detector 3 provided substantially coaxially with the laser unit of the reflected light detector 3.

Then, the light amount a substantially coaxially reflected is reduced. This makes it possible to reliably detect whether or not the adhesive 4 has been applied to the inner surface 5 of the cylindrical aluminum drum 1.
In addition, as long as the reflected light detector 3 can detect the amount of light, the light detection unit does not have to be substantially coaxial with the laser irradiation unit.

Although the surface roughness of the inner surface 5 was set to 0.7 μm, it was sufficient that the irradiation light did not cause regular reflection. As a result of the test, a good result was obtained when the surface roughness was 0.5 μm or more. Further, the angle of the adhesive ejector 2 with respect to the inner surface 5 may be horizontal. However, when the adhesive ejector 2 returns to the original position after the ejection, the adhesive is easily separated from the tip of the ejection. The larger the angle, the better.

When the adhesive is applied to the inner surface 5 and spreads, the discharge of the adhesive discharger 2 is stopped.

At this time, as shown in FIG. 1, by irradiating the laser light from the reflected light detector 3 from above the adhesive discharger 2, the projected area of the coating surface 5 as viewed from the reflected light detector 3 becomes large. Thus, the discharge amount can be detected more accurately.

In the second embodiment, the reflected light detector 3 is movable between a position indicated by a two-dot chain line and a position indicated by a solid line. The laser irradiation position f when the reflected light detector 3 is at the position indicated by the solid line is deeper than the laser irradiation position g when the reflected light detector 3 is at the position indicated by the two-dot chain line. When the discharge amount of the adhesive 4 is large, the reflected light detector 3 moves from the position indicated by the two-dot chain line to the position indicated by the solid line, and detects a change in the reflected light amount of the adhesive. As described above, by moving the laser irradiation position of the reflected light detector 3, the discharge amount of the adhesive 4 of the adhesive discharger 2 can be controlled.
